Hello everyone I have a HP Probook 4520s that I got. When I plug it in with the charger (not the right charger its a 65w but I need a 90w) I get a indicator that was orange saying it was charging I guess. Every 5 or 10 secs it would blink white and attempt to power on but when it trys to power on the power button lights up and the internet button lights up for half a sec and then cuts off. Then it changes back to orange and repeats. After a while of charging the orange light turned white. The white every 5 secs would go off and then return to white. I would attempt to turn it on nothing would happen rather than the power button lighting up and then cutting off in under a second. After awhile the white indicator completely went off for good. When I plug in the laptop I have no indication.... When I attempt to power it on, same thing happens. If I hold the power button for about 10 secs without the charger plugged in the power button turns white for around 5 secs (monitor does not come on) then power button cuts off. I opened up the laptop and the only thing I could see that was wrong was there was no hard drive. (That's all I realized, I'm new to opening laptops but very experienced at desktops.) What is wrong with my laptop? It has a i3 and 2gbs of ram that I'm willing to upgrade if I can get it too work... I just want to watch YouTube on this laptop. My father got me this laptop from his job for free, so why not try to get it to work?
